If it receives data it needs, And processes it. It will bundle and send to server, state will change to Online.

F- are supplied boxes from FR24, not software based like you are working on. They are live and able to report connection data

Gotcha...

something doesn't look or feel right about this in TCP mode. as u see in RTL1090, a plane is shown on my map transmitting. it never was sent to fr24feeder. I went back to the default mode and shut RTL1090 off for now. it started tracking correctly now.

Either format output from RTL1090 is not in right mode, or the signal is not good enough. FR24 is configured for filtering and will only respond to a constant feed, patchy or not very good signal will be ignored.
